“…The homogeneity score increases when each cluster contains only the same labels as are possible, as shown in Equation (8). The completeness score aims to include all given labels in one cluster and is calculated by Equation (11).…”

“…Such malfunction is known to be an immediate cause of a decrease in productivity on a manufacturing shop floor [10]. Facilities are usually interdependent at the shop-floor level, as a product goes through multiple facilities for manufacturing [11]. Therefore, a malfunction of one facility is critical to the entire processing line, as it affects other facilities.…”

In recent years, manufacturing companies have been continuously engaging in research for the full implementation of smart factories, with many studies on methods to prevent facility failures that directly affect the productivity of the manufacturing sites. However, most studies have only analyzed sensor signals rather than text manually typed by operators. In addition, existing studies have not proposed an actual application system considering the manufacturing site environment but only presented a model that predicts the status or failure of the facility. Therefore, in this paper, we propose a real-world failure prevention framework that alerts the operator by providing a list of possible failure categories based on a failure pattern database before the operator starts work. The failure pattern database is constructed by analyzing and categorizing manually entered text to provide more detailed information. The performance of the proposed framework was evaluated utilizing actual manufacturing data based on scenarios that can occur in a real-world manufacturing site. The performance evaluation experiments demonstrated that the proposed framework could prevent facility failures and enhance the productivity and efficiency of the shop floor.

This paper describes research conducted in the context of an industrial case, dealing with the design of reconfigurable, cellular manufacturing systems. Reconfiguring such systems represents a complex task due to the interdependencies between the constituent subsystems. A novel, computational tool was developed to support the production engineers in (sub)system configuration by enabling to consider multiple alternative configurations simultaneously. The tool was tested by applying it in two realistic system engineering problems and conducting interviews to evaluate its effects. The prototype was found to be an effective and efficient approach to support exploring, evaluating and selecting sets of system configurations. The findings suggest that the approach is applicable in practice and represents a means to strategically leverage the flexibility in production system design, as well as to improve the efficiency of the engineering process. Hence, further research could examine if the approach is useful in additional systems engineering domains.
